The radical mechanism explains why the bromination of butane results in a racemate.. When a hydrogen atom is extracted from butane by an attacking bromine atom, it does not matter which hydrogen is extracted, an achiral planar sp.

Paper No. 1: ORGANIC CHEMISTRY - I (Nature of Bonding and Stereochemistry) Module 1 3 : Cyclodextrins Part - I Know More Glossary C Cyclodextrins: Cyclodextrins (sometimes called cycloamyloses ) are Chirality, Isomerism, & Stereoisomerism. Lecture No.. 1. What is the difference between an enantiomer and a diastereomer?. Enantiomers and diastereomers are two types of stereoisomers. Enantiomers include mirror images and non-superimposable chiral centers. Diastereomers contain non-superimposable chiral centers, but are not mirror images. Depending on the number of stereocenters, there could be far more than 2 compounds.. . Dr. Geeta Singh. Assistant Professor. Department of Chemistry. D.D.U. Gorakhpur University, Gorakhpur. 1. .
